Ngaphakathi kwishishini elikhulu lemichiza, iikhompawundi ezithile zidlala indima ephambili ekudaleni iindidi zeemveliso esizisebenzisayo yonke imihla.Enye yekhompawundi eziguquguqukayo ezinjaloiacetyl chloride.Nangona isenokungaqheleki kubantu abaninzi, olulwelo lungenambala noluthukuthezayo lunokubaluleka okukhulu ngenxa yeempawu zalo ezizodwa kunye nokusetyenziswa.Ukusuka kumayeza ukuya kwincasa kunye neziqholo, i-acetyl chloride izisa amathuba angapheliyo koosonzululwazi kunye nabaqambi.Kule bhlog, siphonononga umdla we-acetyl chloride kunye nendlela eguqula ngayo ishishini lemichiza yanamhlanje.
I-Synthetic Versatility:
I-formula yekhemikhali ye-acetyl chloride yi-CH3COCl kwaye iyinxalenye ebalulekileyo kwi-organic synthesis.Umsebenzi wayo oyintloko ulele kwinkqubo ye-acetylation, esetyenziselwa ukwazisa iqela le-acetyl (-COCH3) kwiintlobo ezahlukeneyo.Ngokusebenzisa i-acetyl chloride, izazinzulu zinokutshintsha ukwakheka kunye neepropathi zeamolekyu ezahlukeneyo zendalo ukuphuhlisa amachiza amatsha, idayi kunye neepolymers.I-reactivity yayo kunye namaqela ahlukeneyo asebenzayo, afana ne-alcohols kunye ne-amines, yenza ukuveliswa kwezinto ezixabisekileyo, ukuvula umnyango kwiindlela ezintsha ze-chemical synthesis.
Usetyenziso lwamayeza:
Ukubaluleka kwe-acetyl chloride kwishishini lamachiza alikwazi ukugqithiswa.I-acetyl derivatives yamachiza okwenziwa ahlala ephucula i-bioavailability, uzinzo, kunye nokusebenza kakuhle.Ukongezelela, i-acetyl chloride inceda ukudala i-acetylating agents, ezibaluleke kakhulu kwi-synthesis ye-antibiotics efana ne-chloramphenicol kunye ne-penicillin.Impumelelo yale nkqubela phambili yamachiza yabalelwa kusetyenziso olukrelekrele lwe-acetyl chloride.
Iincasa kunye neziqholo:
Ishishini lencasa kunye nevumba lixhamla kwisakhono se-acetyl chloride ukukhupha kunye nokuguqula iikhompawundi ezibalulekileyo.Ngokusabela ngobulali kunye neengqungquthela zendalo ezifumaneka kwizityalo, i-acetyl chloride inceda ukudala i-esters, i-ketones, kunye ne-aldehydes ezijongene nevumba elimnandi kunye neencasa esidibana nazo imihla ngemihla.Nokuba livumba elihlaziyayo lesepha yesitrasi okanye ivumba elinkcenkceshela emlonyeni leemveliso ezibhakiweyo, iacetyl chloride ishiya uphawu olungacimekiyo kumava ethu oluvo.
Imiyalelo yokhuseleko:
Nangona ukubaluleka kwe-acetyl chloride akunakunakwa, kubalulekile ukuba uqaphele ukuba le ngqungquthela idinga ukuphathwa ngokucophelela ngenxa yezinto ezinobungozi kunye netyhefu.Kufuneka kusoloko kuthatyathwa amanyathelo afanelekileyo okuzikhusela, njengokunxiba izixhobo ezifanelekileyo zokuzikhusela nokuphatha kwindawo engena umoya.
I-Acetyl chloride yikhompawundi ephawulekayo eqhuba izinto ezintsha kwaye iqhubela phambili imboni yeekhemikhali.Ukuguquguquka kwayo kunye nokusebenza kwakhona kuyenza ibe yinto ebaluleke kakhulu ekudityanisweni kwamayeza, iziqholo, iziqholo kunye nezinye iimveliso ezingenakubalwa.Njengoko abaphandi beqhubeka nokuphonononga amandla ayo angenamkhawulo, i-acetyl chloride ngokungathandabuzekiyo iya kuhlala iyisithako esiphambili ekubumbeni ihlabathi lanamhlanje.Ngoko kwixesha elizayo xa usonwabela ivumba elimnandi lekhandlela olithandayo elivumba limnandi okanye uthathe iyeza lokuthomalalisa ukungonwabi, khumbula igalelo elimangalisayo le-acetyl chloride, iqhawe elingavunywanga kwishishini lemichiza.
